App Membrane Bituminous Membrane

APP modified bitumen waterproofing membrane. This product is used for protecting buildings from water infiltration, typically on concrete flat roofs or roofs with a low pitch. The membrane is manufactured from bitumen modified with APP (Atactic Polypropylene) polymer, which enhances flexibility and heat resistance. It is reinforced with a non-woven polyester carrier to boost mechanical characteristics like tensile strength and tear resistance. The rolls in the image have a weight specification of 4.5 kg/m2 and are described as "Grey Mineral". They are designed to provide a flexible, watertight layer that is fully bonded onto the surface.
